TlI three-dimensional coordination polymer involving tetranuclear cubic cage nodes, [Tl4(μ8-SB)2]n{H2SB = 4-[(4-hydroxyphenyl)sulfonyl]-1-benzenol}

The single crystal X-ray analysis of a novel TlI coordination polymer of 4-[(4-hydroxyphenyl)sulfonyl]-1-benzenol (H2SB) ligand shows that the complex is a three-dimensional polymer as a result of bridging “SB2−” ligands with basic repeating [Tl4(μ8-SB)2] units. There are four thallium atoms with different coordination spheres in the cubic cage. These thallium atoms contain irregular coordination sphere with stereo-chemically active lone pair and thallium–thallium interactions, Tl(1)O4, Tl(2)O4Tl2, Tl(3)O4Tl and Tl(4)O3Tl.
